Needed help on java script and html in PL/SQL doing nothing

Question

Hi,
Created a procedure which takes username and password and changes OID, database password for that user with that password.
I created a page in oracle portal and trying to call this below script package:
BEGIN
user_name := portal.wwctx_api.get_user;
HTP.p
     <!-- BEGIN CODE FRAGMENT -->
     <script language="javascript">
     <!--
     function ValidatePass()
     var passStr = document.getElementByid("p_password").value;
     var confPassStr = document.getElementByid("Confirm_Password").value;
          var pattern = /[^a-zA-Z0-9]/;
          if (passStr == null || passStr == "") {
               alert("Password value missing");
               return;
          if (confPassStr == null || confPassStr == "") {
               alert("Confirm password value missing");
               return;
          if (passStr.match(pattern) == null && confPassStr.match(pattern) == null) {
               if (passStr == confPassStr) {
                    document.form.submit();
               } else {
                    alert("Your entries did not match. Please try again!");
          } else {
               alert("Invalid charcters entered");
     //-->
     </script>
     <form name="changepassword"
     action="http://<hostname>:7777/pls/sys/sys.gx_user_mgt.globally_update_password"
          method="post" AutoComplete="Off">
<input type="hidden" name="username" value=" '
|| user_name
|| ' " id="p_username"/>
New Password:
<input type="password" name="p_password" id="p_password">
<br>
<br>
Confirm Password:
<input type="password" name="Confirm_Password" id="Confirm_Password">
<br>
<br>
<input style="padding:2px;" type="submit" value=Login onClick="ValidatePass();">
</form>
END;
This gx_user_mgt.globally_update_password is the custom procedure I should call passing username and p_password
Thanks in advance.

Friends I want to try something but I am totally lost on how to achieve it.Just to let u know that I have not worked in JAVASCRPT at all.And I am in great hurry to finish this work.
What I am looking for is :
1) a JSP page is thrown
2) a button is clicked
3)Moment the button is clicked I want a file to be created with an extension HTML (having all the info from the database) by using FileWriter class .After the file is created and ready ,Then I want to open this file in another browser window.
I know that to achieve this I have to use Javascript,but I am totally lost on how to do that.
I mean can I say in JAVASCRIPT that if this button is clicked then execute a java method which retrives data from the oracle database in the server and writes it to a HTML file and then after the writing is done,open it another window.
Please help.
